Hello again to everyone reading this post. Well I came across the question which I cant solve. Pls help :( Given the quadratic equation (k+3)x^2+(6-2k)x+k-1=0 Find the values of k for which this equation will have one root six times the other Thanks in advance!! :')

Hi i was just graphing trigonometric functions when I came across a cosine function with a period of 3pi. I also came across another cosine function with a period of 2pi/3. So my question is: how do you exactly graph theses? Functions with period of 2pi, pi etc... are real easy but these I...

Hi to everyone reading this thread. I was wondering what the graphss would look like or the following: 1. y=(|x|)^3+1 2. y=|x^3+1| 3.|y|=x^3+1
